Question

Programming in C# I got an Xml.XpathNodeList object “ResultsPartRel.nodeList”. Debugging it with Visual Studio I can read “Results View ; Expanding the Results View will enumerate the IEnumerable”

Questions:

1.- Which is the best way to read those nodes?

2.- I program the next code but I dont get the expected results. I get the same result twice. (ResultsPartRel.nodeList contains 2 nodes)

         List<string> childrenName = new List<string>();

         foreach (XmlElement node in ResultsPartRel.nodeList)
         {
             string nameChildren = node.SelectSingleNode("//related_id/Item/keyed_name").InnerText;
             childrenName.Add(nameChildren);
         }

Thank you in advance.

EDIT

<related_id>
  <Item>
    <classification>Component</classification>
    <id></id>
    <keyed_name>glass</keyed_name> <!-- I want to get this InnerText -->
    </Item>
</related_id>

Well we really need to see the XML sample and a verbal explanation of which data you want to extract. Currently you do a node.SelectSingleNode(...) so that looks as if you want to select a path relative to node but then you use an absolute path starting with //, that is why you get the same result twice.

So you want node.SelectSingleNode(".//related_id/Item/keyed_name") or perhaps even node.SelectSingleNode("related_id/Item/keyed_name"), depending on the XML you have.
